Provides conversion suitable for astrophysics, ultra-high vacuum, and cryogenic applications
Examples
-
2 poundal/square foot converts to 2 × 1,488,163,943,569,500,000 attopascal [aPa]
-
0.5 poundal/square foot converts to half of the conversion factor in attopascal [aPa]
Common Use Cases
-
Translating historical FPS pressure data into fine SI units for modern analysis
-
Quantifying extremely low pressures in astrophysics or space physics research
-
Describing residual gas pressure in ultra-high vacuum systems
-
Supporting theoretical and computational models requiring ultra-small pressure measurements
Tips & Best Practices
-
Carefully handle large numerical values to avoid precision errors
-
Use this conversion only when dealing with pressures far below typical laboratory or atmospheric levels
-
Verify unit appropriateness for your scientific or engineering context before using attopascal values
Limitations
-
The large conversion factor reflects vastly different pressure scales and requires caution when interpreting results
-
Attopascal units apply primarily to extremely low pressures and are not common for everyday or atmospheric measurements
Frequently Asked Questions
-
Why convert poundal/square foot to attopascal?
-
Converting to attopascal permits expressing extremely low pressures in scientific fields like astrophysics and ultra-high vacuum technologies where high precision at tiny scales is essential.
Key Terminology
-
Poundal per square foot
-
A pressure unit from the FPS system representing one poundal of force distributed over one square foot of area.
-
Attopascal [aPa]
-
An SI derived pressure unit equal to 10^-18 pascal, used to describe extremely small force per unit area.
